CHUTE-SPRING FOR MATRIX-ASSEMBLING MACHINES, &c.

SIFEGIFICATION forming part of Letters Patent No. 659,322, dated October 9, 1906.

Application filed Tune 9, 1900. Serial No. 19,704. (No model.)

T0 at whom it may concern:

Be it known that we, FRANK J. RENZ and LYNNE COLLINS, citizens of the United States of America, residing at St. Paul, State of Minnesota, have invented certain newand useful Improvements in Chute-Springs for Matrix- Assembling Machines, &c. and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to matrix or type assembling machines, and is particularly useful in connection with what are known as circulating linotypemachines, in which the usual form of matrices or of type having notches or V-shaped recesses at their tops are caused to descend through channels converging to a common throat or assembling-chute, at the bottom of which they are successively urged forward into the usual assembling-galley by a suitable pusher until a line of matrices or type is completed, from which the this spring with means whereby the matrices,

&c.,are prevented from turning in their course and assuming a position transverse to the assembling-chute, whereby they would clog the assembling-chute and interfere with the operation of the machine,and whereby the travel of the matrices, &c., in the correct path from the channels to the assembling-block will be insured with certainty and positively.

Another object of the invention is to prevent injury to the sides of the matrix or type at the point where the character is located, there being a danger under the old form of chute-spring of pressing or indenting the sides of the character by striking the sharp bend back of the fork in the old style of spring.

With the above objects in view a chutespring embodying our invention is provided with a tongue arranged between the two prongs of the forked shoulder of the spring and extending downward below the same. This tongue effectually prevents the turning of the matrices or the like above referred to and at the same time does not prevent the advance of the said matrices, &c., into the assembling-block, by virtue of the fact that these matrices in their usual form are provided with notches or V-shaped recesses at their tops into which the tongue extends, thereby permitting the said matrices to clear the tongue. At the same time this tongue prevents the matrices from striking against the sharp bend of the fork, whereby the character 0n the same may receive injury. The

latter result is, moreover, aided under this invention by longitudinal ribs or other raised portions arranged at the end or lower part of niodified forms of chute-springs under our invention; and Fig. 6, a transverse section on line 6 6, Fig. 5.

In the drawings, ct represents the guideways of a machine for assembling matrices, &c., through which the latter pass on their way from the magazines to the throat or assembler-chute A. At the bottom of the throat A is arranged the usual assembling-block B and pusherin the present instance in the shape of a star or cam wheel Cwhich pusher serves to force the matrices or the like into the assembling-block as they successively enter the space between the said pusher and assembling-block, the arrangement, construction, and operation of these parts being well known.

The forward wall of the assembler-chute is in part formed by the assembler-chute spring D, which is the particular subject-matter of our invention.

As seen from Figs. 2 and 3 the assemblerchute spring D consists of a piece or strip of spring metalsuch as brass. steel, or the likewhich may be provided in the usual manner with the slots (1 (Z at its shank portion d for securing it to the matrix-delivering portione. 9., by screws (Z (1 Figs. 1 and 2. The lower portion of the same is suitably shaped in the usual manner to form one wall of the assembler-chute and is provided with the usual forked shoulder, consisting of the two prongs or shoulders d (1 at the edges of the chute-spring, which are bent transversely to the direction of the said spring-i. 6., in a direction substantially the same as the line of feed of the matrices E as they are pushed forward in the assembling-block l5.

Thus far the chute-spring described does not differ from the spring in use. Our invention consists in providing the lower end of the chute-spring with a downwardly eX- tending tongue F, which is so arranged that it will extend into the V-shaped notch or recess c, with which the matrices E are usually provided. Under the present arrangement of matrices this tongue is therefore arranged centrally on the end of the chute-spring, as shown. The object of this tongue is to prevent the matrices E from turning or tilt ing as their forward or lower ends pass the fork d d and before they reach the proper place in front of the line of matrices in the assem bling-block,\vhere they are compelled to maintain their proper position prior to being advanced into the assembling-block. Such turning or tilting of the matrices would block the further delivery of the following matrices and cause delay or result in transposition of matrices. This tongue holds the matrices in their proper position until the pusher C begins to act on them, and at the same time it does not prevent their being turned into the vertical position and advanced into the assembling-block B, because when they have reached the properpoint in their descent the tongue F clears the recess 6 of the matrix. Moreover, the said tongue prevents the side walls of the character e from being pressed, dented, or otherwise injured by rubbing or striking against the bend (Pof the fork (Z3613, since said tongue holds the matrix away from such bend or corner at the time the character 6 passes such bend. This is a very importantfunction, since the side walls of the characters stamped on the edges of the matrices are very delicate and any indentation of them would in casting allow the metal to flow between the matrices at the point where such indentation was made, thus forming sprues or fins. Besides this, the appearance of the cast and printed letter would sulfer.

The latter function of the tongue may be considerably aided in many cases by providing the lower end of the chute-spring D with a raised portion or boss, which may be in the form of longitudinal ribs G G, preferably arranged one on each side of the tongue,as shown in Figs. 2 and 3, such ribs extending from a sufficiently-elevated pointg on thelower portion of the spring, where they preferably merge in the surface of the spring, down around the lower bend d to the lower end of the spring These ribs may be formed in the spring by stamping, embossing, or in any desired manner. The ribs are arranged in such a manner that the character e on the matrix E extends laterally beyond the same, so as not to come into contact therewith. Another arrangement of the ribs is shown in Fig. 4, where these ribs G are represented as extending upward beyond the second bend d, where the usual cross-bar(1,terminatingin the usual stud d', is secured to the spring, as is well understood. Under this arrangement the danger of wearor injury to the sides or walls of the character on the matrix, which also exists to some extent at the bend d, is still further reduced. Another modification of the reducing-boss is represented in Figs. 5 and 6, where the middle longitudinal portion G of the lower part of the chute-spring is represented as elevated or raised above the surface of the spring, the tongue F forming a prolongation of this raised portion.

By referring to Fig. 6 it will readily be seen how the part of the matrix E bearing the character is held away from the bends in the spring.

- It will thus be seen that the device embodyint. our invention may be considerably modified without departing from the said invention.

The boss or raised portion at the lower part of the spring may have many forms and arrangement-s, and it may consist of one or several elevations. Such elevations may or may not be formed at the second bend d, the latter being the preferred arrangement.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

1. In machines for assembling matrices, type and the like, an assembler-chute spring provided with a tongue extending from the end thereof.

2. In machines for assembling matrices, type and the like, an assembler-chute spring provided with a lower forked shoulder in combination with a tongue extending below said fork.
